RESUMO
Objective: The extract technologies for the components of Fuzhuang Capsules were optimized. Methods: Four methods: the semi bionic extraction (SBE), the water extraction (WE), the semi bionic extraction by precipitation with alcohol (SBAE) and the water extraction by precipitation with alcohol (WAE) were used to extract Fuzhuang Capsules, with panaxadiol, panaxatriol, ? sitosterol, icariine, betaine, total sugar and dried extractive taken as the marker, under the same conditions of drug granularity, solvent amount, decocting temperature, filtration, concentration, etc., and then four methods were compared and studied. Results: Through the comprehensive evaluation of seven markers, their comprehensive values Y decreased in the order of SBE, WE, SBAE and WAE. Conclusion: SBE is better than the other three methods in the extraction of the components of Fuzhuang Capsules, which is showed by the fact that the pH values of the water for the 1st, 2nd and 3rd decoctions are 3.4, 7.5 and 8.4, and the extraction times are 2.0h, 1.5h, and 1.5h respectively.
